The ash of the dung is about double that of the re¬ 
fuse hay. The alfalfa fed was the second crop, and the 
chemical analysis shows that it was too ripe when cut; 
alfalfa cut earlier would show better results as to its feed¬ 
ing qualities. It took, in the case of No. 1, 18 pounds of 
hay to make one pound of increase of live weight; in the 
case of No. 2, it took 10J pounds, or an average of both 
animals of 14 pounds. 
By way of illustration, the digestibility of the crude 
fiber is worked out for No. 1 for the 13 days: 
No. 1 ate 312 pounds of hay; it contained 9.75 per 
cent, of moisture; equals 281.58 pounds of dry hay; this 
hay contained 19.92 per cent, of crude fiber—56.09 
pounds of crude fiber. The refuse hay was 5 6-13 ounces 
a day=4.43 pounds. This refuse hay contained 23.6 per 
cent, of crude fiber=1.04 pounds. Subtracting this from 
50.09 pounds, leaves 49.05 pounds of crude fiber the ani¬ 
mal ate. The dung averaged 54.625 pounds a day, or 
710.125 pounds ; it contained 17.1 per cent, of dry dung 
= 121.43 pounds; this contained 22.47 per cent, of crude 
fiber=27.28 pounds of crude fiber ; subtracting this from 
the amount of crude fiber in the hay, leaves (49.05-27.28) 
= 21.77 pounds digested by the animal, or, expressed in 
per cent., equals 44.3 per cent. 
In a similar way, all the other ingredients were worked 
out.
